Do you have the driver activated? To check, go to:
System > Administration > Hardware Drivers

For my Dell Studio 1557, which is also Win7/Ubuntu 10.04 with BCM4312, I had to activate the "Broadcom STA proprietary wireless driver". I'm fairly certain I got it working from the disc but, at worst, you'll need a wired connection for a minute or two to download it. Once installed, it prompts you to restart, though you may be able to use it by just logging out and in again.

Hi,

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following command from the https://answers.launchpad.net/ubuntu website in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word restart. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo aptitude update; sudo aptitude install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'ound|irmware|eth|ath|wl|ipw|b43|witch|ndiswrapper'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo /etc/init.d/networking restart

Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.

Regards,

Mark

The following output shows that your wireless card is disabled by a hardware wireless killswitch:

  *-network DISABLED
       description: Wireless interface
       product: BCM4312 802.11b/g

0: dell-wifi: Wireless LAN
 Soft blocked: no
 Hard blocked: yes

There should be a hardware wireless button on your PC that you need to press to turn wireless ON.

During the boot phase, also check in the BIOS if there is an option to set wireless to "enabled" or to "by application".

Can you help with this problem?
